How to calculate the area? Please tell me.

A= D (B+(B+2nD)/2).
Here D = 2
B = 1.6
n = 1( which is given as slope 1:1 we will take the base i.e horizontal)
So, Area = 7.2.

It is very simple guys:
The formula for Area of trapezoidal tank =Bd +sd^2.
B - width.
d - depth.
S - slope(1vertical is to 1 horizontal i.e, =1).
So, Area is (1.6 x 2)+(2^2)=7.2.
So 7.2/.025 = 288.

Area = 7.2 sqr-m.
Perimeter= 7.252 m.
Hydr. R = 0.99 say 1.
Assume the slope of 1 in 100.
V = 1/0.025 x (1) ^ 2/3 x (1/100)^ 1/2.
V = 4 m/sec.
Q = A x V.
Q = 7.2 Sqr-m * 4 m/sec,
Q= 28.8 cumec.

2a+4b is equal to 7.2.
where a = 0.4.
b = 1.6.
where a = 0.4.
b = 1.6.
